Yamaha kodiak 400 no start scenario 2003
Hello.
I'm new to the forum and I have an issue that I hope someone could kindly help me with. I received a 2003 Yamaha Kodiak 400 4x4 ATV. It was running great, however over the last couple months it started having a harder time starting. Now it will not start at all. I have tested the stator and it has checked out with the proper ohm readings on all 3 legs, I have replaced the coil and spark plug. When I check the plug for spark, it only sparks after i release the start button. Does not spark during the cranking cycle, only after the cycle is finished. I am positive it is getting fuel. Is this a timing issue? How best to rectify this problem? Thank you any help or direction in this matter.

"it only sparks after i release the start button"
This is a common problem on CDI ignition and nobody seems to have a definitive answer. Some say it is a dirty or faulty trigger coil for spark timing. I did find, on a Honda, that the CDI needed the neutral signal from the neutral light circuit, or it did this. I don't mend enough Yams to know if they have a wire from neutral light circuit to CDI. Make sure your earths are good on frame, engine and battery too.
